My 8 KW Onan diesel generator has a coolant recovery bottle that fills as the coolant heats up (expansion tank). In the past, the level of the coolant in the bottle would rise about an inch and a half as the generator worked under load.
I flushed the raw water system with Barnacle Buster and since that treatment the coolant level in the bottle does not rise at all. The generator runs perfectly, the temperature sits at 176 degrees. Is this unusual or is it a good thing? I did check the level of coolant by opening the coolant cap on the generator itself and it is right up to the top.
Thanks, Howard
